Add a sending domain
Add a new sending domain to a tenant. Returns DNS records that must be configured before the domain can be verified.
Each tenant gets their own isolated mail server for domain isolation.
Required DNS records:
- SPF - TXT record for sender authentication
- DKIM - TXT record for email signing
- Return Path - CNAME for bounce handling
After adding DNS records, call POST /tenants/{tenantId}/domains/{domainId}/verify to verify.
